Do These Envelopes Any Physical Or Historical Value?

Do these envelopes any physical or historical value?

Yes, they are lovely covers/entires and the Bloods Penny post covers are highly collectible. Great Bloods hand stamp on the 2nd cover.

Surely in the hundreds of dollars if all prove genuine.

You may be interested in this brief biography pertaining to the top cover, addressed to Henry A. Coit, 44 South St., New York City:

Yes! All of them have value. The Blood stamps are known as locals.

They appear to be Scott nbr 15L13, acid-tied.

The British cover at the bottom has an example of a Bishop Mark and dates from sometime after 1713 (because the month is in the lower segment). There may also be a possible part Charing Cross Receiving House mark.

Four different covers:
1 - Stamp is the 1849 New York City Carrier stamp Scott catalog number 6LB9. It has a catalog value of $100 or so. It is not tied to the cover, so may have been applied later. Had it been tied to the cover by a cancellation, it would have a catalog value of about $350. You will need to have an expert look at it to determine whether both the stamp and cover are genuine.
2 - Stamp is probably the 1850 Blood's Local Post stamp Scott catalog number 15L13. Private local posts competed with the post office for business. As you can see, it was never handled by the post office. It is acid tied to a cover and has a catalog value as such of $75. Bloods was one of the larger companies and operated in Philadelphia.
3 - Similar - Different Blood's Local Post stamp (note the difference in the last line - "Dispatch" becomes "Phila"(delphia) - From about 1854 and with a similar value.
4 - This looks British to me. That type of datestamp is classically British. Also, is that a partial "Charing Cross / London" handstamp under the flap?

Hope that helps.
